Rhythmic activity during sleep may get fluids in the brain moving. //
Human brains (and those of other higher organisms) evolved to have billions of neurons in the functional tissue, or parenchyma, of the brain, which is protected by the blood-brain barrier.
Everything these neurons do creates metabolic waste, often in the form of protein fragments. Other studies have found that these fragments may contribute to neurodegenerative diseases such as Alzheimer’s.
The brain has to dispose of its garbage somehow, and it does this through what’s called the glymphatic system (no, that’s not a typo), which carries cerebrospinal fluid that moves debris out of the parenchyma through channels located near blood vessels. However, that still left the questions: What actually powers the glymphatic system to do this—and how? The WUSTL team wanted to find out.
To see what told the glymphatic system to dump the trash, scientists performed experiments on mice, inserting probes into their brains and planting electrodes in the spaces between neurons. They then anesthetized the mice with ketamine to induce sleep.
Neurons fired strong charged currents after the animals fell asleep. While brain waves under anesthesia were mostly long and slow, they induced corresponding waves of current in the cerebrospinal fluid. The fluid would then flow through the dura mater, the outer layer of tissue between the brain and the skull, taking the junk with it.
The promise of AI, we hear over and over again, is that it’s a tool to help humans do better, automating tasks to free up worker time for other things. But instead, AI looks far more like HAL 9000 in “2001: A Space Odyssey,” a computer that overtakes its human masters’ ability to control it and turns against humanity. //
Behind the scenes and out of sight, AI and social media algorithms can be used to determine what you are allowed to post, what you will be able to read, and ultimately what you will think.
Despite the promises of simplifying workflows and managing tasks, there’s far too much evidence of AI destruction to be ignored.
When it comes to AI, be afraid, be very afraid.

The lattice splitting pad may be used to combine two audio sources into a single audio output or to derive two separate outputs from a single audio source. A characteristic of the lattice pad that makes it very desirable for audio work is the port to port isolation. When used as a splitter, output port to output port isolation is theoretically infinite if the pad resistor values match the input port source impedance. In combiner applications, input port to input port isolation is also theoretically infinite if the pad resistor values match the output port load impedance.
First: Eliminate withholding. Everyone, every quarter, has to send money to the IRS. Everyone gets their entire paycheck and then has to pay up. The withholding system is too painless; most people scarcely glance at their paycheck stub, and if everyone were required to write a check for quarterly estimated taxes and send it to the various levels of government, I'd wager a substantial sum that they would suddenly become a lot more interested in what government does with their money.
Second: Eliminate “progressive” taxation. Implement a single-rate flat tax with no exemptions or deductions for individuals. Everyone pays something. I’d be willing to consider exempting the first, oh, $40k from taxation, if that’s what it took to get it done – in return, I’d want major welfare reform, to include lifetime limits and severe restrictions on how public aid is delivered – no more open-ended debit cards.
Third: How about eliminating the capital gains tax next? You want people to invest their hard-earned in business ventures, then stop double-taxing them on income earned from money they already paid taxes on once. Want businesses to start bringing capital back from overseas? Eliminate the capital repatriation penalty. Both of those taxes are well to the left of stupid if economic growth is on the agenda, but these taxes were sold by the “We’ll soak those rich guys” school of political campaigning.
In 2023, China really knocked the wind out of the sails (hah) of the renewable-energy crowd. In that year, China built some new coal-fired electrical generation facilities. In fact, they built a lot of coal-fired electrical plants — as in...more than twice that of the rest of the world combined.
China ramped up coal power capacity last year, according to new analysis, despite a pledge to "strictly control" the dirtiest fossil fuel.
The country added 47.4 Gigawatts (GW) of new coal power in 2023, more than double the amount added by the rest of the world combined.
Sen. Rand Paul (R-KY) appeared on "Sunday Morning Futures" with Maria Bartiromo and alleged a whistleblower revealed that at least 15 government agencies were aware that gain-of-function research on viruses was being conducted at the Wuhan Institute of Virology in China as far back as 2018.
The 23 million-acre petroleum reserve on the North Slope was set aside as an emergency oil supply, originally for the U.S. Navy, by President Warren Harding.
In 1976, in accordance with the Naval Petroleum Reserves Production Act, administration of the reserve was transferred to the Department of the Interior’s Bureau of Land Management (BLM) and renamed the NPR-A.
President Joe Biden is on the verge of locking down half of it, making it unavailable for oil and gas development. He intends to do so with a new rule that is proposed by the Biden Administration through the Bureau of Land Management, a division of the Department of Interior.

Iran informed Turkey in advance of its planned operation against Israel, a Turkish diplomatic source told Reuters on Sunday, adding that the US conveyed to Iran via Ankara that its operation must be "within certain limits."

There's no way to sugarcoat that. The Biden administration told the Iranians it was acceptable to attack "within certain limits." Were those limits adhered to? That's something only the president and his handlers can answer (and never will), but given their rush to demand Israel not strike back, it would seem probable that everything went according to plan. //
This is a betrayal that is hard to fathom. //
Whatever Iran has on Biden and the entire Obama alumni must be incredibly serious given the links these people are going to to protect a terrorist state. //

That may be true, but there is another possibility which is at least equally unsettling: there’s a “balanced” foreign policy mindset among a good deal of the DC elites, that requires their definition of all competing interests getting what they decide is a proper share. Part of this has to do with crackpot notions of proportionality, part of it is a craven hope that by carefully managing everything, stability, if not outright peace will be maintained. These wise f*ls actually think they are clever and orchestrating a grand scheme, all while fluffing their own egos and feathering their own nests. While the truth is they are weak and stupd.
So it’s not so much they are being blackmailed, although that’s possible, but more likely they are literally giving it away for free.
But then a disturbing report came out that the reason the U.S. had such good intel about an Iranian attack on Israel was because it was Iran who tipped the Biden team off. But they told the U.S. that they would consider it limited and not escalate if Israel didn't respond. The Biden team told Israel they would not be involved in an offensive attack on Iran and was encouraging Israel not to respond, to "take the win" from their good defensive response to the attack. They were also leaking about the discussions to the media, undercutting Israel and saying they didn't know if Israel would sit back after being attacked. //
Washington had conveyed to Tehran via Turkey that any action it took had to be "within certain limits." Basically, you were having Joe Biden green-lighting the attack.
As you may have noticed, I’m a fan of history. So, I’ll close with a piece of historical trivia:
Only one man has ever been both president (1909-1913) and then on the Supreme Court, weighing 320 pounds at 5-foot-11. That was Ohioan William Howard Taft, who liked steaks so much he would at times have one at every daily meal.
Taft was a friendly man, the first president to own a car, and the last to keep a cow at the White House for fresh milk. He also began the presidential tradition of throwing out the first baseball of a new season.
Taft lost reelection in 1912 to Woodrow Wilson and Theodore Roosevelt. In 1921, President Warren Harding named him Chief Justice.
Taft took retirement in February 1930. It was brief. He died one month later.
Re: They Took Way Too Long To Port It
Personal view, so no [AH] tag or anything:
The Linux kernel is an extremely rapidly moving target. It has well over 450 and nearly 500 syscalls. It comprises some 20 million lines of code.
It needs constant updating and the problem is so severe that there are multiple implementations of live in-memory patching so you can do it between reboots.
Meanwhile, VMSclusters can have uptimes in decades and you can cluster VAXen to Alphas to Itanium boxes and now to x86-64 boxes, move workloads from one to another using CPU emulation if needed, and shut down old nodes, and so you could in principle take a DECnet cluster of late-1980s VAXes and gradually migrate it to a rack of x86 boxes clustered over TCP/IP without a single moment of downtime.
Linux is just about the worst possible fit for this I can imagine.
It has no built-in clustering in the kernel and virtually no support for filesystem sharing in the kernel itself.
It is, pardon the phrase, as much use as a chocolate teapot for this stuff.
VMS is a newer and more capable OS than traditional UNIX. I know Unix folks like to imagine it's some eternal state of the art, but it's not. It's a late-1960s OS for standalone minicomputers. Linux is a modernised clone of a laughably outdated design.
VMS is a late 1970s OS for networked and clustered minicomputers. It's still old fashioned but it has strengths and extraordinary resilience and uptimes is one of them.
Re: Linux needs constant updating
Yeah, no. To refute a few points:
Remember, there are LTS versions with lifetimes measured in years.
Point missed error. "This is a single point release! We are now on 4.42.16777216." You still have to update it. Even if with some fugly livepatch hack.
And nobody ever ran VMSclusters with uptimes measured in years
Citation: 10 year cluster uptime.
https://www.osnews.com/story/13245/openvms-cluster-achieves-10-year-uptime/
Citation: 16 year cluster uptime.
Linux “clusters” scale to supercomputers with millions of interconnected nodes.
Point missed. Linux clusters are by definition extremely loosely clustered. VMSclusters are a tight/close cluster model where it can be non-obvious which node you are even attached to.
Linus Torvalds used VMS for a while, and hated it
I find it tends to be what you're used to or enounter first.
I met VMS before Unix -- and very nearly before Windows existed at all -- and I preferred it. I still hate the terse little commands and the cryptic glob expansion and the regexes and all this cultural baggage.
I am not alone.
UNIX became popular because it did so many things so much more logically
I call BS. This is the same as the bogus "it's intuitive" claim. Intuitive means "what I got to know first." Douglas Adams nailed it.

Thinks of why Windows nowadays is at an evolutionary dead end
Linux is a dead end too. Unix in general is. We should have gone with Plan 9, and we still should.
"When my team and I went to South Korea, we were floored at the level of digitization and real-time monitoring of shipbuilding progress, with readily available information down to individual pieces of stock materials," Del Toro said.
"Their top executives could tell us to the day when ships would be delivered," he said. That's a stark difference from the US, which is facing problems with its shipbuilding capacity, labor availability, and resources. //
During his recent Sea Air Space speech, Del Toro further praised South Korea and commended Japan, saying both Pacific allies could build high-quality ships on time, on budget, and often at a fraction of the cost. //
Maj. Jeffrey L. Seavy, a retired US Marine Corps officer, wrote for the US Naval Institute that China had roughly 47% of the global market on shipbuilding, the most of any country, with South Korea coming in second at about 29% and Japan in third at about 17%. He said the US had "a relative insignificant capacity at 0.13%," referencing numbers from the United Nations Conference on Trade and Development.
U.S. forces in the area have reportedly shot down "dozens" of drones targeting Israel. They've also reportedly taken out missiles, as well. //
Israel says most launches were taken out outside of Israel. //

Catching up now after Shabbat. Obviously missed a lot. Here are my quick takeaways:
1) Iran’s attack against Israel — 200+ drones, cruise and ballistic missiles — more aggressive and pervasive than expected.
2) Israel’s response so far has been magnificent — intercepting 99% of the incoming.
3) Lots of help provided by USA, UK, France and even Jordan. We are grateful.
4) Iran literally attacked the Al Aqsa Mosque. Had Israel not intercepted the missile, 3rd holiest site in Islam destroyed.
5) This is the time for Israel, the West and the moderate Sunni nations to unite against this evil, terrorist nation.
